WILLIAM E. WALKER AND GEORGE E. WILBUR, OF TAUNTON, MASS.

HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 329,516. dated November 3, 1885.

Application tiled Derember 22, 1884. Serial No. 150,907.

To all whom it may concern:

Beit known that we, WILLIAM E. WALKER and GEORGE E. WILEUR, both of Taunton, in thel county of Bristol and State of Massachusetts, citizens of the United States, have invented new and useful Improvements in Heating-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forminga part of this specification, in explaining its nature, in which- Figure I represents in vertical section a heating-stove containing the features of our invention. Fig. 2 is also a vertical section at right angles to the view shown in Fig. l. Fig. 3 is a horizontal section on the line y y of Fig. 2. Fig. 4 is a plan view of the base portion of the stove with the upper base-plate removed to show the arrangement of ues. Fig. 5 is a plan view below the line of the ash-pit plate. Fig. 6 is a vertical section of the base portion ofthe stove upon the line m x of Fig. 3.

The invention is represented as applied to the class of heating-stoves known as indirectdraft heating-stoves, or stoves which have ues extending downward from the combustion-chamber to the base and from them to the uptake.

In the drawings, A is the ash-pit; B, the firepot; C, the combustion-chamber; D, the outer casing of the Inain portion of the stove, and D the base section of the stove. E E are downues on either side of the stove, connecting the combustion-chamber with the baselues e e. These base-dues extend along the sides of the base from the front to the dotted line e2 shown in Fig. 3, and, through the openings e3 in the ash-pit walls e, connect with the base-flue e5 beneath the ashpit plate (No model.)

e6. The flue e5 extends backward upon the dotted lines el, Fig. 3, .to the uptake es. Below the plate e9, forming the bottom of the liuc e5, is the liuc or passage F, the under or lower surface of which is the bottom plate, f. This ue is open to the outer air at f', (see Figs. 2 and 6,) and extends backward, and then laterally outward at f2, (see Fig. 6,) and enters the chamber ,f3 at each of the back corners ofthe stove, (and the cover.) Air which enters through the' hole or aperture f is heated by coming in contact with the plates which separate this cold-air passage from the base-dues and ash-pit, and it escapes through the holes f in the upper base-plate at each back corner. (See Figs. 3 and 6.) These holes f t may be closed by registersf, if desired.

The inlet-holes f6 may be provided in the back base-plate of the stove, if desired.

The grate and oven-cover, which formed a part ot' the original application, have been withdrawn by amendment, and Iliade the subject-matter of separate applications.

Having thus fully described our invention, we claim and desire to secure by Letters Patent of the United Statesl. The combination, in a heating-stove, of the fire-pot B with the ilues c e c5, the coldair passage F f 2 f 3, and outlets f, all substantially as and for the purposes described.

2. In a heating-stove, the combination of the fire-pot B with the basesection D', having the Hue-plates e* e5 e9 f3, which form the base-dues and cold-air passages, substantially as specified.
